Description

A three-dimensional light steel frame composed of continuous and discontinuous double side beams

technical field

The utility model belongs to the technical field of light steel buildings, in particular to a three-dimensional light steel frame composed of continuous and discontinuous double side beams.

Background technique

Light steel buildings using light steel roof trusses have entered a period of rapid development and have been widely used in industrial buildings. Light steel housing has become a new field and new growth point for light steel structure applications. At present, the cost of light steel buildings is generally higher than that of traditional concrete structures, but they have competitive advantages such as fast construction, energy saving and emission reduction. More and more construction units have realized the superiority of light steel structure, and it has gradually become the preferred structural form of industrial buildings, and it has also been widely used in low-rise civil buildings.

Light steel buildings using light steel roof trusses still have great improvements in terms of architectural design, structural design, and manufacturing and installation techniques. The light steel roof truss structural beams and structural columns currently used are generally connected by butt joints (such as fixed joints or hinged joints). Since a large number of structural beams, structural columns, etc. are used in the light steel roof truss of this structure at present, this docking method makes the bonding process complicated and serious error accumulation occurs at the same time. The same applicant submitted a utility model patent with the patent number 200920171128.9 on August 20, 2009, and the name is "light steel roof truss with continuous double beam structure". However, the patent still has the following shortcomings: the patent does not involve a three-dimensional light steel frame system composed of continuous and discontinuous double side beams, and at the same time, it is difficult to assemble the three-dimensional frame, and the structural strength of individual components and the overall frame is insufficient. In addition, the continuous double girders in this patent cannot meet the needs of different cross-sections in response to different stress conditions, resulting in waste of materials. The connection among them adopts continuous double-beam overlapping combination. The continuous double-beam connecting member is too long to cause difficulty in frame assembly, and the two-way continuous double-beam overlapping combination causes space waste and causes uneven stress on column-beam joints.

In addition, the same applicant submitted a utility model patent with the patent number 201520052886.4 on October 21, 2015, and the name is "three-dimensional light steel roof truss composed of two-way continuous double beams". But this patent still has the following deficiencies: 1. This patent does not involve the three-dimensional light steel frame system formed by the continuous and discontinuous double side beams described in this patent. 2. The patent is limited to purlins and/or purlins, floors, roofs, and reinforced lightweight composite floors. 3. This patent does not relate to the connection of the continuous and discontinuous single-sided beams described in this patent with the columns or beam-to-column connectors at the web. 4. This patent does not involve the continuous double-side beam described in this patent further adopting a discontinuous single beam, and the discontinuous single beam is selected from channel steel, square section steel, open square section steel, round steel pipe, and truss beam. 5. This patent does not involve a three-dimensional light steel frame system composed of continuous and discontinuous double girders described in this patent, further setting reinforcement components, the reinforcement components are between the two side beams, And/or all or part of the concrete is poured between the cavities of the columns, and the concrete is further provided with stirrups and steel rods for strengthening the concrete.

Square steel components commonly used in the field of light steel construction generally use square steel pipes. The bolt holes connecting closed square steel pipes to other components can only be processed by drilling or flame cutting, and cannot be stamped by punching machines, resulting in high processing costs; closed square steel pipes cannot be connected with other components using locking high-tension bolts. Thereby greatly reducing the bearing capacity of the joint. In order to prevent rust and corrosion, the square steel pipe is generally galvanized after processing, which leads to high production costs. If two galvanized steel sheets are rolled and formed by C-shaped steel for butt welding, this processing method will destroy the anti-rust layer of the galvanized steel sheet. The invention patent with the patent number 201010216616.4 filed by the same applicant on June 30, 2010 and titled "Square Light Steel Member with Reinforcement Parts" solves the above problems, but there are still the following deficiencies: the technical solution of this patent is practically used When the internal cavity of the square steel pipe is filled with concrete or cement mortar, the compressive strength of the column section is far greater than the overall pressure bearing capacity of the column determined by the slenderness ratio of the square steel pipe column, that is, the The concrete or cement mortar has not reached the compressive damage and the reinforcing parts do not work, so the reinforcing parts are not necessary, and the square light steel members equipped with the reinforcing parts cannot be fastened during transportation, wasting transportation space and transportation cost.

In view of the above-mentioned defects in the existing light steel structure, the inventor, based on his rich practical experience and professional knowledge in the design and manufacture of such products for many years, combined with the application of academic theory, actively researched and innovated, in order to create a new structural light steel structure , making it more practical. Through continuous research, design, and after repeated trial samples and improvements, the utility model with practical value is finally created.
